elevated position, and to this end it consists, Referring to Figs. l and 2, A represents broadly, in combining with the guide for the portions of the main frame; B, the lower end upper ends of the reeds or with other means of the stationary inclined magazine, Consistrear with the respective escapements D. The

upper reed-guide F is mounted on horizontal pivots f, so that it may be swung forward and backward in order that the reeds may be thrown backward from their operative position (shown in Fig. l) to the position shown in Fig. 2 out of engagement with the escapements. The reeds E terminate at their lower ends above the inner ends of corresponding yokes H, mounted to rise and fall on IiXed pivots /L at theirouter ends. Each yoke is slotted vertically to receive a cam I, turning on a pivot c' in the yoke. J J represent two continuously-rotating rubber-covered rolls extending transversely of the keyboard beneath the respective series of yokes and cams for the purpose of engaging and turning the cams I. Angular dogs K serve to hold the respective yokes normally at such height as to maintain the cams I out of engagement with the underlying rolls, the cams being in the meantime prevented from rotating by the engagement of internal shoulders with fixed stop-pins L. Each dog K is connected by a vertical slide M with a linger-key lever N. Vhen a finger-key is actuated, the dog releases the corresponding yoke H and permits it to fall until its cam I disengages from the stop L and rests upon the underlying roller. The frictional engagement of the roll causes the cam to turn on its center, the result of which is that the cam lifts the yoke above its original position, causing it in turn to lift the reed E and release the escapement D, the position of which is immediately reversed by the spring CZ bearing thereon. The dog resumes its original position under the yoke, which is arrested in its descent, while at the same time the cam is arrested in its rotation, so that these parts stand again in their original position, the reed E being at the same time drawn downward by a spring O, so that the escapement D is compelled to resume its first position.

All of the foregoing parts are constructed and operate as usual.

My first improvement relates to means for preventing the reeds E from falling below the level of the escapements when they are disengaged therefrom, as shown in Fig. 2. In the form shown the locking device consists simply of an arm P, fixed rigidly in the frame in position to engage a stud Q, applied for the purpose to one of the reeds E Or to aspecial sliding bar mounted in like manner. I/Vhen the parts are in operative position, the stud Q stands in front of the locking-arm P, so that it is impossible to swing' the reed-guide and reeds backward.

R represents the usual reed-supporting bar, which is separate or distinct from the machine. Its inner end is beveled and it is adapted to be thrust through an opening in the main frame into position beneath the series of yokes H in order to hold them and the reeds resting upon them at or slightly above their ordinary operative position, as shown in Fig. 2. I provide the bar with a raised surface r or otherwise form it in such manner that when thrust inward to support the reeds it will lift the reed or slide it across the locking-stud Q until the stud is above the locking-plate P, as shown in Fig. Q, the effect being to lift the parts free, so that the reed-guide F may be swung rearward in the ordinary manner to the position shown in Fig. Q. I

The essence of my invention consists in providing means whereby the upholding of the reeds is rendered positively necessary prior to their disconnection from the escapements, and it is manifest that the details of construction to this end may be widely varied.

The reed-guide is held normally in position by a latch f2, which is of ordinary construction and foreign to the present invention. This latch of course requires to be unlocked, as usual, before the guide can be moved.

Referring to the second part of my invention, (illustrated in Figs. 3 and 4,) the escapements, reeds, reed-guide, &c., are of the same general organization as in the preceding figures, like parts being indicated by like letters in all the figures. For the purpose of locking the entire series of escapements be'- fore the magazine is removed from the machine to prevent accidental release of the matrices I mount in the under side of the magazine the transverse rock-shaft S, cut away on one side in such manner that when turned into the position shown in Fig. 3 it permits the free action of the escapements, but when turned into the position shown in Fig. 4 it bears upon their rear ends and locks the entire series rigidly against movement, so that the escapements in turn lock the matrices positively within the magazine. not claimed as a part of the present invention, which relates to the means for actuating this device or its equivalent. I provide this rock-shaft on the outer end with a crank-arm s, entering a slot in the horizontal upper end of a bar T, mounted to slide vertically in guides on the main frame. Thelower end of this bar is provided with a stud 2f, adapted to enter a notch on a hand-lever U, mounted on one end of a horizontal rock-shaft V, sustained in the main frame, so that whenever This device in itself is- IOS IIO

the lever is raised the intermediate parts will turn the rock-shaft and lock the escapements and in like manner unlock them when the lever is depressed. Across the series of reeds near their lower ends Vl extend a horizontal bar lV. carried at its ends by vertical guides y//- on the main frame and adapted to enter notches fi in the rear edges of the reeds. these notches being of such width verticall,v as to permit lost motion of the parts that the reeds may serve their ordinary function while the bar is at rest. This bar serves to lift and sustain the reeds in the same manner that they are sustained by the bar lt in Figs. l and ln other words, it is an equivalent to the removable bar l, but a permanent member of the machine. 'lhe guides at the ends of the bar are formed with shoulders or proiections fr, overlying crank-arms w, secured to the rock-shaft Y, as plainly shown. lVhen the hand-lever is thrown upward, the cranks w underride the projections '/l.: and lifting the bar lV cause it to lift and sustain the entire series of reeds. 'lhe formation of the arms '/f-'i and the location of the shaft V are such that after the lever is raised, as shown in Fig. il, the parts will remain in place, and thus lock the reeds in their elevated position. lt will be observed that this upward movement of the lever to lift the reedsalso causes the action of the escapement-lockingl device. The reed-guide F is locked in position by means of the stud Q and fixed locking-plate l) until the reeds are elevated to carry the stud out of engagement with the plate, as described in connection with Figs. l and The upward movement of the lever serves the threefold purpose of lifting and sustainingl the reeds, of unlocking the reed-guide from the plate l that the reeds may be disengaged from the escapements, and of locking the escapements, so that the accidental release of the matrices is prevented. 'hcn the magazine is to be removed from the machine, it is necessary to disengage the crank .s from the actuating-arm T. '.lo this end the upper horizontal end of the arm is in the form of a sleeve fitting over the horizontal end of the body portion and arranged to be moved Yforward and backward by hand, so that it may be engaged and disengaged at will. This sliding portion slotted and secured by a tluunb-screw, as shown. The reed-guide F may be provided with an upwardly-extending arm f in position to underride the crank .v when the guide is thrown backward, as shown in Fig. l, that the interl r cking of these parts may prevent the reed-guide F from being moved until the crank has been turned upward out of the path of the armf to lock the eseapements, and, on the other hand, the crank will be prevented from turning to unlock the escapements until the guide has been restored to its normal operative position and the arm f thereby carried from under the crank-arm. lVhen the lever U is turned to its uppermost position, it will disengage from the stud l. In order prevent the bar '.l` from falling out of position, it is notched and a spring-latch fi mounted on the Yframe toenter the notch, as shown in Fig. 3, It will be observed that when the handle U is raised the reeds are lifted and locked in an elevated position, the escapements locked to hold the matrices within the magazine, and the reed-guide unlocked to permit the disconnection of the reeds fromthe escapements. In this manner the operator is not only enabled but compelled to place the parts in positions of safety before removing the magazine, and this without appreciable loss of time. The return movement of the handle U after a magazine has been placed in position and after the reed-guide F has been swung forward to its operative position will restore the various parts to the operative condition. The handle U lies adjacent to the keyboard in such position that it may be conveniently reached and operated by the compositor. This handle and its coi'inections for liftingl and locking the reeds in the elevated position are of great :nlvantage aside from the other parts with which they cor'perate in that they enable the operator to lock the reeds up and render the keyboard inoperative. The improper release of the matrices by the accidental or mischievous operation of the keys in the absence of the operator is thus prevented.

Having described my invention, what I claim isl.
